new and useful Improvements in Detachable Fasteners, of which thefollowing speci fication. 'i This invention relates to fasteners, andnmore particularly to detachable fasteners, and has for its object to.provide a fastener Aincluding hook and eye elements andl'rad andresilient socket elements so arranged Ithat, after the hooi: and" eyeelements have been mutually engaged, the head and socket elements may bemutually engaged to prevent disengagement of the hook and eye,

While the latter prevent casual disengag ment of the ball and socketelements.

Another object is to provide a fastener of this kind which may bemanufactured at a loW ligure and which will yet be highly eliicient.

Other objects and advantages will be apparent from thefollowingdescription, and it will he understood that changes in thespecific structure shown and described be made Within the scope of theclaim Without departing from the spirit of the inven- So tion.

- which it is made.

Referring new to the drawings, the pres ent invention comorlses .oooksocket Y i vmember eye and head member 5. The eye member is formed of asinglelength of Wire including a slightly curved central portion 7 atopposite sides of which there are upwardly directed loops 8 occupyingacommon vertical plane, and beyond the loops the end portions of thepiece of Wire are bent to form horizontally disposed attaching eyes 9,The upper port-ions of the loops 8 are somewhat Wider than their lowerportions, as shown, and the loops are thus held within hollowv metallicheads l0,

. having openings 11 in their lower ortions, through which the ondportions ol' he loops extend. There is thus a head 1G located at ueachside of the portion .7 which 'forms a hoolr receiving eye o the usualtype.

The member 5 includes a'hook which. is formed' of a length of Wire bentupon itself to produce parallel portions 12 and 13, connected bya`loight 14C. from the bight, the portions 12 and 1,3 are lient uponvthenfiselves to produce a hook 15, the bight 14 forming the bill of thehook. Beyond the bill or" the hook 15, the portions toward theirstraight portions to form attaching eyes 16, and beyond these attachingeyes the portions oithe Wire are carried par ".allel to the portions l2and 13 as indicated atl'! to points opposite the sides of the hook 15,Where they are bent upwardly and outwardly as shown at 18 and thendown-`vvardly laterally and again upwardly 'to form eyes 19, beyond whichthey are curved upwardly and outwardly toward the hook 15 as shown at 2Oadjacent to which they are bent downwardly as shown at 21 and againformed into attaching eyes, 18 and 2O are thus oppositely disposed, andare oppositely curved to direct the concave surfaces toward each other,and thus at each side of 'the hook 15, there is formed a resilientsocket. A and these sockets are arranged to receive the heads 10 whenthe hook 15 is engaged beneath the eye 7. When it is desired todisengage the eyes lA from the heads 10, it is only necessary to graspthe eyes 19 through the fabric to which these eyes are attached andsqueeze them together,l when the opposite side portions of the member 5will loe spi-un with respect to each other upon the high 14 as will beunderstood, and the sockets A Will be disengaged 'from 'the heads. Thisresult may be accomplished hy reason of the' fact that the eyes 19 liein a plane below theA plane of the sockets A as illustrated.

What is claimed is:

A two-part fastening device, comprising a hook member having portions ofits mate# rial bent to 'form 'resilient sockets disposed upon oppositesides of the hook, attaching formed interral with the sockets and adiiierent plane so as to space from the material to the At a pointspaced' 13 are curved outwardly and then inwardly The portions willow'eyes me secnrel, an eye member having its fmly engage said sockets ofille hook ends provided with attaching oyos, .im eye member, '10 formedntenlecllno Said eyes, upwardly lln testimony whereof l aflx my eigrmureoled loops disposed between ille interni@ tute, in presence of twoWitnesses.
